Four Nigerian Teenage Girls Develop a Urine-Powered Generator.

Four teenage girls, Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15) have stunned the country with their invention of a urine powered generator at this year’s Maker Faire Africa, an event which shows off innovations, inventions, and initiatives that solve immediate challenges and problems, and then works to support and propagate them. The teenagers’ invention was one of the most remarkable exhibitions at the fair which took place from Monday 5th November to Tuesday 6th November in Lagos.

Remember how we sometimes make jokes when we experience fuel scarcity saying we wished we could use urine to power our generators? Well it might not be a joke anymore if these girls’ invention is given the support it needs.

Here’s how it works:

Urine is put into an electrolytic cell, which cracks the urea into nitrogen, water, and hydrogen.

The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder.

The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.

This purified hydrogen gas is pushed into the generator.

1 Liter of urine gives you 6 hours of electricity

In a breakthrough, four teenage schoolgirls in Nigeria have invented a 'pee-powered' generator that converts one litre of urine into six hours of electricity. Fourteen-year-olds Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin, and 15-year-old Bello Eniola presented their invention at the Maker Faire Africa entrepreneurs event, in Lagos, using a resource that is free, unlimited and easily obtainable.

According to the Maker Faire blog, urine is put into an electrolytic cell, which cracks the urea into nitrogen, water, and hydrogen. The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder, the 'Daily Mail' reported. The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.

This purified hydrogen gas is pushed into the generator, and one litre of urine provides six hours of electricity. Maker Faire blog described the generator as "possibly one of the more unexpected products" at the event. While the system does have one-way valves for safety, more robust measures may be needed before it can be sold widely. The report noted: "Let's be honest that this is something of an explosive device".

Nigeria's economy is on the rise, however, more than half of the country's 162 million citizens have no access to electricity, and even those who do can't guarantee having power every day, the report said.
